I've often seen those low consumption rates when driving around town which is fairly flat at speeds of around 35-45 mph.. I think wind resistance is definitely a factor. Everything has a bearing on the outcom though. I'm thinking about upping the tire pressure to around 48 and see if it...
I read that when you receive this error you could try initiating the charge using the Tesla app and that should initiate the charge. The Ford update for Tesla charging is supposed to fix this issue.
